UNITED STATES PATEN T GRANVILLE NUTTING, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO NEW YORK STANDARD WATCH COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

WATCH-MOVEMENT.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed May 12, 1908. Serial No. 432,368.

T 0 all whom it may concern:

Be it known that I, GRANVILLE NUTTING, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have made and invented certain new and useful Improvements in atch-Movements, of which the following is a specification.

My invention relates to an improvement in watch movements, and more particularly to improvements upon that described and illustrated in the atent to J. Petrillo, No. 755,313 and dated March 22nd, 19-04. As many thousands of these movements have been constructed and put into daily use, and as the construction and operation is well known to those skilled in the art, the description of the several parts and their op erations, will be confined to those elements which I have improved upon, and to which my invention particularly relates.

It is well known that during the manufacture and adjustment of the different parts of a watch movement, it often arises that it has to be taken down and reassembled several times before completion, and my experience in the manufacture of the patented movement above referred to, has taught me that considerable time and labor is involved in taking said movement down and re-assembling and adjusting the parts, particularly as they are nearly all attached to either the top or pillar plates, as described in said patent.

The purpose of my invention is to overcome this objection by having certain of the parts slide freely on the plates, and held in their proper relative positions by means of other parts pivoted or secured to either the dial or top plate.

A further obi ect of my invention is to reduce the number of parts, and thereby materially simplify and decrease the cost of manufacture.

VJith these and other ends in view, the invention consists in certain novel features of construction and combinations of parts as will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the upper side of the top plate with its accompanying mechanism, the parts being shown in their several adiustments after the split second hand has been returned to its normal position or to the ing out of mesh with the split second wheel. Fig. 2 is a sectional view taken on the line 22 of Fig. 1. Fig. 3 is a view of a portion of the mechanism in that adjustmentwherein the driving pinion is in mesh with the split second pinion, and the ily-back lever thrown out by the star wheel, allowing the split second Wheel to be rotated by the driving pinion. Fig. 4 is a similar view showing the driving pinion out of mesh with the split second wheel. Fig. 5 is a sectional view taken on the line 55 of Fig. 1. Fig. 6 is a plan view showing the driving pinion, split second wheel, and the heart-shaped cam attached to the latter. Fig. 7 is a view of the sliding click and its arm 19 lying between the windirig bridge and the collar formed on the dial ate. iii the fly-b achiever. Fig. 9 is a similar view of the shipper lever. Fig. 10 is a detached view of the starting and stop ing mechanism in one of its adjustments. *ig. 11 is a simi lar view of the same mechanism in a different adjustment. Fig. 12 is an edge view of the mechanism shown in Fig. 10, and Fig. 13 is a.

sectional view of a part of the mechanism showing the arrangement of the sliding click and means for holding the same in position by the arm of the ratchet pawl spring.

In the patented movement the shipper lever and spring which carry the driving wheel into and out of engagement with the driven wheel are made in one piece, and held at one end by a screw to the frame. This construction and arrangement I have found objectionable by reason of its cost, the danger of breakage, and the labor involved in taking down and assembling the several parts.

In the present instance, as clearly illustrated in the several figures of the drawings, I construct the shipper or driving pinion lever and the spring for operating the same,in two separate pieces, in order that the latter may be made suiliciently heavy and strong throughout its length to properly perform its functions and avoid any danger of breakage or injury when the watch is accidentally.

dropped. This shipper lever A, shaped as illustrated in Fig. 9, is provided at one end with a stud a adapted to fit in a socket formed in the top plate l3 and held in position by means of the spring O, one end of the latter being secured to the top plate B and number 12 on the dial, the driving pinion bethe opposite or free end bearing upon the shelf aformed on the lever A near its pivoted end, the tendency of this spring being to hold the driving pinion D carried by said 1e.- ver, in mesh with the driving or split second wheel E, and at the same time hold the lever down and retain the stud a in its socket.

It will be understood from the above that in order to remove the shipper lever and driving pinion D carried thereby, it is simply necessary to lift the free end of the spring 0 from the shelf a, whereupon the lever and pinion may be at once removed, the spring remaining attached to the plate B. .Again, in the patented movement, the fly-back arm or lever is pivoted to the plate B by means of a screw, but in my improved device it will be seen that such fly-back lever F, (a detached view of which is shown in Fig. 8), is arranged somev. hat similar to the lever A, that is, is provided on one end with a stud f adapted to fit in a socket formed in the top plate B, and with a shelf f projecting from one side thereof, and on which latter rests one end of thefly-back lever spring G, the opposite end of the spring being secured to the plate B by means of the screw 9 The tendency of this spring G is to force the free end f of the lever F into contact with the heart-shaped cam H, and also to hold the lever down in place and retain the stud f in its socket in the top plate B, the great advantage in this construction and arrangement of parts being that in order to remove the fly-back lever i it is simply necessary to raise the free end of the spring G from the shelf f, whereupon the said lever may be easily and readily removed.

In order to simplify the winding and setting mechanism, the sou are winding arbor 14. is extended downwardly into the sleeve 15 formed with the winding pin-ion 16, the inner end of said arbor bearingagainst one end of the round push pin 17, the opposite end of the latter in turn bearing against the sliding click 18. T his click 18 is provided with an integral arm 19 extending upwardly between the winding bi idge 20 and a collar 21 formed on or secured to the dial plate 25, and through which collar passes the screw 22, the latter also passing through the ratchet pawl spring 23, the opposite or free end of said spring engaging with the ratchet v heel 24, w ith which the sliding click also engages, as clearly illustrated in luigs. 10 and 11.

Instead of pivoting the arm 19 to the dial plate 25 by means of a screw, as is usually done, the same is left free and held in its proper place by means of the arm 26 formed integral w ith the spring 23, as clearly illustratedin Big. 10. By this construction and arrangement of parts, the cost thereof is materially reduced and permits of their ready removal and. assembling.

The sliding click 18 has formed thereon or secured thereto the pin 27, with which engages one end of the click spring 28, the said spring being fastened by means of the screw 29 to a post 30 formed on or secured to the dial plate 25, as illustrated in Figs. 10, 11 and 12, the opposite end of the click spring being held in a slot formed in the winding bridge 20., The tendency of this click spring 28 is to force upwardly or backwardly the sliding click 18 after the latter has been pushed inwardly or downwardly by the winding arbor 14 and push 3111 17, the parts being so arranged that the sliding click is not only allowed a movement in line with the movement of the push pin and winding arbor, but also a lateral movement, in order to clear the teeth of the ratchet wheel 24 when the click is returned to its normal position by means of the spring 28. In taking down this part of the movement, it is simply necessary to remove the springs 23 and 28, whereupon the sliding click may be readily lifted from its place.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
